Zhijie Shen updated YARN-422:
-----------------------------

    Attachment: YARN-422.10.patch

Thanks, Vinod! Addressed most of your comments except the following:

won't be a performance bottleneck as it is called when NMClient stops.

The biggest change is using state machine in the newest patch.
